External grinding is used for grinding of cylinders and surfaces on the outer diameter of cylindrical parts. With our automated, highly productive CNC external grinding machines with a variety of grinding methods such as CBN peel grinding or corundom plunge grinding we have the ability to deliver high-quality yet economical production of a wide range of wave-shaped parts.
The ability to create gemstones in the laboratory began in 1902 when Auguste Verneuil, a French chemist, developed a method known as flame fusion to create synthetic ruby. This was no mere laboratory experiment. Verneuil soon expanded his lab into a full scale production facility and was turning out 1,000 kg of synthetic corundom by 1907. 041b061a72
